Apple also built remote attestation into their browser, I don't think they care much about FOSS neckbeard hackers. They probably see the same privacy and security risks and didn't see a reason to go along with the rest.

Apple is perfectly fine with taking control of your privacy if they're the ones in control, and in this case they would have to put third parties in control instead. I'm sure they'd much rather take control themselves and build these types of checks into their "Sign in with Apple ID" buttons instead, so they can put "if you want Human Proven Secure Attested devices (invented by Apple), let your users sign in with Apple ID" on their website.
